11 Claims. (Cl. 53-120) This invention relates to a machine of extremelysimple construction by means of the operation of which coupons areautomatically inserted into cartons, after closing of the cartons.

More particularly, it is an aim of the present invention to provide acoupon inserter which is best adapted for use in inserting coupons intofilled cartons of the so-called end tuck type after the end closure flapis in a closed position; however, the machine is also adapted for usewith other types of cartons and for inserting a coupon therein eitherafter or prior to complete closing of. the carton.

Another object of the invention is to provide an inserter which isreadily adapted for use in applying coupons to cartons of the type inwhich butter and oleomargarine are packaged and which, due to its uniqueconstruction, may be readily attached to a conventional packagingmachine and driven by a novel power takeoff from the drive of suchmachine, although the inserter is additionally adapted for use alone andmaybe readily operated by any available rotary driven shaft.

Various other objects and advantages of the invention will hereinafterbecome more fully apparent from the following description of thedrawings, illustrating a presently preferred embodiment thereof, andwherein:

Referring more specifically to the drawings, the coupon insertingmachine in its entirety and comprising the invention is designatedgenerally 10 and includes a base 11 which, in the application and use ofthe invention as herein 2,821,823 Patented Feb. 4, 1958 flange 15 at itsupper end which is secured by fastenings 16 to an upstanding rearportion 17 of a supporting bracket, designated generally 18. Thesupporting bracket 18 has a forwardly extending bottom portion 19 whichextends from the lower portion of the rear part 17 thereof and whichterminates in a front portion 20 which is disposed transversely withrespect to the forwardly extending portion 19. The front portion 20includes a horizontal bottom flange 21 and an upstanding inner flange22, which flange 22 rises from the inner or back edge of the bottomflange 21, as best illustrated in Figures 1 and 2. The standard 14 hasan upper rear portion in which the intermediate portion of a bearingsleeve 23 is secured, so that the axis of said sleeve is disposedcrosswise to the plane of the standard 14, as best illustrated in Figure3. A shaft 24 is journalled in the sleeve 23. As seen in Figure 3, thesleeve 23 has a lubricating port 25 in an upper portion thereof.

The bottom edge of a bar 26 is suitably secured to the upper surface ofthe base 11 in spaced apart substantially parallel relation to thestandard 14. A bar 27 is secured detachably to the outer side of theupper portion of the bar 26 by fastenings 28 and has an upperlongitudinal edge portion disposed above the upper edge of the bar26'and which is provided with a longitudinally extending inwardlyopening groove or channel 29. The bar 27 constitutes one of a pair ofguide strips, the other strip 30 of which is detachably secured to theinner side of the standard 14 by fastenings 31 and at a level so thatthe inwardly opening longitudinally extending groove 32 thereof isdisposed at the same level as the groove 29. Grooves 29 and 32 provideguideways for slidably receiving the longitudinal side edges of anelongated plate forming a blade carrier 33. As best seen in Figures 2and 9, the rear end of a blade 34 is secured in overlapping relation tothe forward end of the carrier 33 by fastenings 35. Blade 34 forms anextension of the carrier 33 and is of a lesser width than said carrier,as seen in Figure 9.

As seen in Figure 2, an angular bracket 36 has a horizontal leg 37adjustably secured by a fastening 38 to the upper side of the base 11and longitudinally thereof. The other shorter leg 39 of the bracket 36extends upwardly from the leg 37 and is disposed to the rear of the base11. One end of a pull spring 40 is anchored to the bracket leg 39 andthe other end thereof is secured to a depending extension 35a of one ofthe fastenings 35 for urging the carrier 33 and blade 34 rearwardly ofthe machine 10. An abutment or cushioning member 41 is secured to theinner side of the upper portion of the upright bracket leg 39 and isdisposed in the path of movement of the rear end of the carrier 33, tobe engaged thereby for limiting movement of said carrier and blade to aretracted position under the biasing action of the spring 40.

The carrier 33 is provided on its upper side adjacent its rear end witha rearwardly facing detent shoulder 42 behind which normally engages apawl 43 forming the lower leg of a bell crank which is pivotally mountedat its apex by a pivot element 44 to the lower end of a lever 45, asbest illustrated in Figures 2 and 3. The upper end of the lever 45 isfixed to an end of the shaft 24 to swing in unison therewith, as bestseen in Figure 3. A spring 46 is wound on the pivot element 44 and hasone end extending upwardly therefrom and bearing against themachineframe.

Alever stop 51 is detachably fixed to and extends inwardlyfrom the standard l4, above the stop 50, for .a purpose which willhereinafter be described.

A disk-like valve member 52 has a bracket arm 53 secured by a fastening54 to a lug 22a of :the bracket portion 22 and is thus supportedimmovably relative to A pipe constituting a hollow shaft and designated55 extends through and is journalled in the central portion of the valvemember 52and has a disk-shaped movable valve member 56 fixed theretoanddisposed on one side of the stationary valve member 52. The ends of thehollow shaft 55 are closed and sealed by detachable caps 57. A lever arm58 is detachably and adjustably fixed to one of the caps 57 'and extendsupwardly therefrom. The hollow shaft 55 is provided with a tubularextension 59 which communi-" cates with. the bore thereof and'whichextends downwardly therefrom, adjacent the other cap 57. An-expansioncoiled spring60 is disposed on the pipe 55 between the stationary valvemember 52 and the cap 57 to which the lever arm 58 is secured, forurging theshaft 55 through the valve member 52 in a direction fordisplacing the valve 56 toward said valve 52,'as best seen in'Figure 6.

As seen in Figures 5 and 6, the stationary valve member 52 has anelongated arcuate groove 61 disposed therein and which opens through theside thereof which faces toward the valve member 56. A nipple 62 extendsfrom a part of the periphery of the valve member 52 and connects with anend of a suction conduit 63 whichleads from any suitable source ofsuction, not shown. The other end of the bore of the nipple 62 extendsinto the valve member 52 and communicates with the groove 61 thereof.The valve member 52 is also provided with a bleeder port -64 whichextends transversely therethrough and which is circumferentially spacedfrom the groove 61, as seen in Figure 5. The valve member 56 has aradially extending .passage- 65 the inner end of which communicates withthe bore of the hollow shaft 55 and the outer end of which is turnedlaterally to open outwardly through the face of the valve member 56which faces the valve member 52,v as best seen in Figure6.

,The tubular extension. 59, has a lower portion 59a which is disposedata slight angle to the upper portion thereof which extends from thepipe 55, as best seen in Figures 1 and 2. A pair of suction cup members66 is secured to,the.t ubular portion 59a in spaced apartrelation to oneanother. Said members 66 communicate with the bore of the tubular arm 59through inner faces of said members which open inwardly or rearwardlywith respect to the machine and which constitutes the only communicationof the tubular arm 59a with the atmosphere.

A chute, designated generally 67, has a flared upwardly opening mouth 68and includes a front wall 69 and a rear wall 70, flared upper portionsof which form the flared parts of the mouth 68. As best seen inFigure 2,the chute 67 has a closed bottom 71 or may be open at the bottom thereofto rest on a surface of the packaging machine 13, by means of which thelower end of the chute could be closed at the same level as the bottom71 and at a desired level beneath aligned openings 69:: and 70a ofthefront and rear walls- 69 and 70, respectively. The; front wall 69 has aninclined extension 72 which extends upwardly from the upper;part thereofwhich forms aportion of the. mouth '68 and which termi- 4 mates in aninturned lip 73 which is secured by suitable fastenings detachably tothe underside" of the bracket portion 21, as seen in Figures 1 and 2. Astrap member 74 extends rearwardly from the lower portion of the chute67 and is secured by a fastening 75 to the forward end of the bar 27 forsecuring the chute immovably relative to the frame of the machine 10.

The inclined wall 72 has inwardly or rearwardly extending side flanges76. The wall 72 is also provided with an elongated slot 77 which extendslongitudinally thereof to accommodate the swinging movement of the tubeportion 59a therethrough, as best illustrated in Figure 3. The slot 77is provided with longitudinally spaced enlarged portions 78 foraccommodating the suction heads 66. A housing 79 is supported by andextends from the forward side of the wall 72 to house the tube portion59a and suction heads 66 in a retracted position of said parts, asillustrated in Figures 1 and 2. The housing 79 has an open upper end inwhich the upper portion ofthe tube 59 is swingablyaccommodated.

-A-lever arm 80 has an upper end fixed to the opposite end of the shaft24 and extends downwardly therefrom. The rear end of a connecting rod 81is pivotally connected to the lower end of the lever 80 andthe forwardendiof said connecting rod 81 is pivotally connected to the outer end ofthe lever 58. The lever 80 is composed of threadedly connectedextensible end sections 80a 'and' 80b, as best seen in Figure 2, wherebythe length 'of said lever and the travel of the connecting rod 81 maybevaried for varying the extent that the hollow shaft 55 is turnedrelative to the extent of turning movement of the shaft 24. An arm 82has a rear end adjustably clamped to the shaft 24, beyond the lever 80.and is provided with a slot 82a at its forward end which is looselyengaged by a fastening 83, carried by the upper end of a connecting rod84 for connecting the rod 84 to the arm 82. The other lower end of theconnecting rod 84 is pivotally connected to one end of a bar 85, as bestseen in Figure 4, the opposite end of which bar 85 is secured detachablyto the connection of a connecting rod 86 to a split ring 87. The ring 87is journalled on a cam disk 88 which is eccentrically fixed to a driveshaft 89 of the packaging machine 13 so that the connecting rod 84 ofthe machine 10 will be reciprocated vertically in unison with theconnecting rod 86 of the machine 13. The upper end of the connecting rod86 is connected to and operates suitable mechanism 96 by which end tuckclosureflaps 97 of cartons 98 are closed immediately before such cartonsare conveyed toward the discharge end of the machine 13 and afterfilling of the cartons.

A magazine or hopper 90 is secured, as by brazing, to the bracket 18adjacent the open bottom of said hopper or magazine. As best seen inFigure 7, the magazine 90 has sidewalls 91 and 92. The side wall 92 isprovided with a relatively Wide slot 92a which extends from end to endthereof. Rod members 93 are secured to the inner-sides of the walls 91and 92 and extend longitudinallythereof and have inturned lower ends 93awhich extend 'to slightly below the level of the open bottom 94 of saidmagazine, as seen in Figure 8. The rods 93 of the wall 92- straddle theslot 92a thereof. The magazine -90 contains a stack oficou'pons 95 whichare supported therein by: the inturnedrodends 93a, as seenin Figure 8.

Assuming that the parts of thefmachine 10 are in the positions asillustrated in Figures l and 2 withthe eccentric cam 88 in a bottomdead'center position and the blunt forwardend ofthe inserter'. blade 34in a fully retracted position behind'the chute67 and in alignment withthe openingsi70a and 69a thereof,-as the eccentric moves upwardly fromits bottom 'dead center position anppward thrust is'exertedby thecam-88,ring87 and bar,85 on ;the j-connecting rod 84-for displacing saidconnecting I rod upwardly to swing the arm: 82' upwardly' for turningtheist-raft. 224.2111 a counterclockwise direction 5 as seen in Figure 1and clockwise as seen in Figure 2. Assuming that a coupon 95 is disposedin the lower portion of the chute 67 so that its intermediate portion isdisposed at approximately the level of the openings 69a and 70a, as theshaft 24 is turned in the aforementioned direction the lever 45 is swungforwardly and as the pawl 43 is engaging behind the detent shoulder 42,the carrier 33 with the blade 34 will be displaced forwardly so that theblunt forward edge of the blade 34 will enter the chute 67 through theopening 70a and will engage the intermediate portion of the coupon 95 sothat said intermediate portion will be carried by the leading end of theblade 34 through the front wall slot 69a. A carton 98 is supported onrails 99, as seen in Figures 1 and 2, in front of the chute 67 and at aproper level so that the inserter blade 34, carrying the folded coupon95, after passing forwardly through the opening 690 will enter thecarton between the flap 97a of its end closure 97 and the top wall 98a,which is located adjacent said closure flap 97a. Further movement of theblade 34 will cause the coupon 95 in its folded condition to be fullyinserted into the carton 98 before the pin 47 strikes the abutment 50.When this occurs, the bell crank 43, 48 will be swung clockwise as seenin Figure 2 about its pivot 44, against the action of the spring 46,which has been urging the pawl 43 downwardly tomaintain it in engagementwith the detent shoulder 42. When the hell crank is thus rockedclockwise against the action of the spring 46, the pawl 43 will belifted out of engagement with the detent shoulder 42 to permit thespring 40 to rapidly return the carrier 33 to its full line retractedposition of Figure 2 with the inserter blade 34 retracted out ofengagement with the carton 98 and chute 67, for a purpose which willhereinafter be apparent. It will be understood that the inserter blade34 is retracted relative to the coupon 95 which is left in the carton98. Almost immediately after the pawl 43 is lifted to disengage thecletent shoulder 42, the lever 45 will contact the stop 51 to prevent alashing forward movement of the lever after the load being propelledthereby is released.

At the same time that the lever 45 is swung forwardly to effect theinsertion of a coupon into a carton 98, the lever 80 is alsosimultaneously swung forward to cause the lever arm 58 and the hollowshaft 55 to be turned counterclockwise as seen in Figures 2 and 5. Thevalve member 56 and the tubular arm 59 will be turned with the shaft 55,the tubular arm portion 59a and the suction heads 66 moving upwardlythrough the slot 77 and enlargement 78, respectively, toward the bottomof the magazine 90. The passage 65 of the valve member 56 will movecounterclockwise from its dotted line position of Figure 5 and will comeinto registry with the right-hand end of the groove 61 before thesuction heads 66 contact the bottommost coupon 95 of the stack ofcoupons contained in the magazine 90, so that said bottom coupon will begripped by the suction heads 66 upon contact therewith and at whichinstant the cam 88 has reached its top dead center positionand the pawl43 has been released from the shoulder 42.

As the cam 88 commences its downward travel, a downward pull is exertedon the connecting rod 84 and lever arm 82 to turn the shaft 24 in theother direction or counterclockwise as seen in Figure 2, so that thelevers 45 and 80 will be turned in the same direction to swingrearwardly. When this occurs, a pull is exerted on. the lever arm 58 bythe connecting rod 81 to turn said lever arm, the shaft 55, valve member56 and the tubular arm 59 clockwise as seen in Figure 2. At thecommencement of this movement, the passage 65 will be in communicationwith the groove 61 near the left-hand end thereof as seen in Figure 5 sothat suction will be maintained in the suction heads 66 as said suctionheads swing downwardly from the magazine 90 with the bottommost couponwhich will thus be extracted from the bottom of the coupon stack andfrom engagement with the rod ends 93a. During the initial portion of thedownward swinging movement of the tube portion 59a the passage 65 willmove out of registry with the groove 61 to shut off the suction.However, the suction will be maintained until the passage 65 thereaftermoves into registry with the bleeder port 64-, whereupon the suction isreleased in the suctionheads 66 and immediately before said suctionheads pass through the openings 78 so that the coupon 95 will bedisengaged and left against the inner side of the inclined Wall 72, fromwhich position it will slide by gravity down into the chute 67 and intothe position occupied by the coupon previously inserted by the blade 34,as previously described. The cycle of operation will be completed whenthe arm 59 is returned to its position of Figure 2. It will be apparentand as previously explained that the inserter blade 34 will be retractedout of the chute 67 before the coupon, last extracted from the magazine90, will have reached a position in the chute 67.

During the last mentioned movement of the shaft 24 and levers 45 and 80,the lever 45 will have returned to its position of Figure 2. As thelever 45 approaches its position of Figure 2, swinging rearwardly orcounterclockwise, the pawl 43 will strike the cam surface 100, whichextends downwardly and forwardly from the upper edge of the shoulder 42,so that the bell crank 43, 48 will be rocked clockwise on its pivot 44against the action of the spring 46 until the tip of the pawl 43 clearsthe rear end of the cam surface 100, whereupon the spring 46 will rockthe bell crank counterclockwise to swing the pawl 43 downwardly behindthe shoulder 42, preparatory to repeating the forward inserting movementof the carrier and blade, as previously described.

The packaging machine 13 includes a mechanism, not shown, actuated byreciprocation of the connecting rod 86 for feeding the cartons 98 fromleft to right as seen in Figure 4 in a step by step motion, so that thecartons after passing the assembly 96, where the closure flaps 97 aretucked in, are next pushed along the rails 99 to the position of thecarton 98, as seen in Figures 1 and 2, where the carton is disposed tohave a coupon inserted. After the dwell period of the carton while thecoupon is inserted, as previously described, said carton 98 is pushed bythe next following carton off of the rails 99 onto the upper flight ofthe belt of an endless conveyor 101, by which the filled cartoncontaining the coupon is conveyed from left to right as seen in Figure 4away from the coupon inserter 10.

It will be readily apparent that the parts 88, 87, 85, 84, 82 merelyconstitute one means for oscillating the shaft 24 to efiect operation ofthe machine 10 and that any other suitable means for oscillating theshaft 24 could be provided. Likewise, other suitable means synchronizedwith the oscillation of theshaft 24 may be provided for intermittentlyfeeding filled cartons to a position in front of the chute 67 so that acoupon can be inserted into the filled carton by operation of themachine 10 as previously described.
